Any suitable machine may be employed to perform the variousoperationswhereby this newly invented shoe vis made, and therefore the machineshown in Fig. 1 is only typical of the kinds of machines which may befemployedA in the manufacture of the new shoe. In Fig. 1 there isprovided 'a plan view of the shoe shown `female die 1 of suitablematerial such as zinc or the like mounted in a base 2 provided with amold cavity 3 having an undercut toe portion 11 adapted to receive a toeportion 5 of a. male die which isY formed of sections 6, 7, thev section6 being provided with the toe portion 5 and the section 7 forming thecurved heel portion that fits in the undercut heel portion 7 of thefemale die. The die sections 6, 7 are provided with complementaryinclined faces 8, 9 re` spectively adapted to seat against one. anotherwhen the die 6, 7 is in the shoe-forming position, the section 7 beingprovided with a, tongue 10 designed to engage a specification of Lenersraient. @Momma nml', i application inea February 21. i917, serial No.150.031.

groove 11 in the'facc 8 o1 the section 6 so as to prevent the section 7from sliding relavtive to said section 6 when the sections are pressureis applied to said die sections. ,l The die sections 6, 'if' are looselyand yieldn ingly connected to one another by a loose connection such asa coil spring lf2 .fastened at its opposite ends to said sections respcctively and `designed to seat in recesses 12', 12 cut into the-.faces 8,9 respectively.

The sdie `1 is provided with a top liet flange-forming face 13 having agroove 14 extending around the mouth of the cavity 3. Above the lattopface 13 of the die 1,

The presser foot.V 15 is provided with a rearwardly and upwardlyinclined face 33 forming a rest and guide along which the male dieslides when said die is moved up and down.

To Complete the Shoe formed as above, all

parts again assunie the retracted p that is necessary is to trim it bycutting off all or part ofithe flange d and, if desired, the upper mayalso be provided with a slit e of which thefedges may be drawn towardonev another byv laces or equivalents, not shown.

.Thus it is seenthat ltliexfinished shoevis formed of a single piece ofleather and is absolutely seamless.

If it is desired to` have a shoe with a heavier sole, a sole f may'befastened to the sole c as in,Fig. Li.

I am not aware that a seamless shoe i'ormed of a single piece of moldedleather has ever been known before this invention thereof, and theforegoing read in connection with the drawings filed herewith willenable those skilled in the art to which this invention pertains to makeand use said n invention.

I claim: p l. The method of making a shoe, which consists in holding themarginal portions y of a piece of leather, and while said leather is soheld producing pressure in various directions against the middle portionof said leather to form the toe and heel portions of an upper and sole.

2. The method of making a shoe, which consists in holding the marginalportions of a piece of leather, while said leather is so held pressinganother portion of said leather first Adownward and thenforward to fornithe toe portion of an upper and sole, pressing another portion of saidleather downward to form the heel portion of an upper and sole, and thenslitting the portion of said upper above the toe portion.
